Aquarium Medicine Dyed

Hey fellas, I used a certain type of medicine to fix my fin rot problem on my neons and discus, and unfortunetly the tank went from a nice combination of colorings, to a strong neon glow.

My first guess is that the fake plants i put in were mostly green so they were radiating a green glow. (This was months after the medicine and many water changes)

I figured out the medicine in the water is gone but the dye remained on the decorations (after i moved a white skull decoration from one tank to another and realized it had a mild green tone on the white).

I took out all the decoration and am slowly soaking it out , cleaned the tank out, keeping watching on the fish however even with nothing in the water still is tinted green, my guess is the glass stained, and I'm wondering if there is a way to remove the green glow without having to remove the fish (i got no spare tank to place 2 discus and 15 neons). And should i add them to other tanks it might stress them out and the inhabitants of those tanks too.

Need help!

I did some more water changes and the water improved, you guys were right the glass was not stained, i figured this out when i dropped alot of the water and looking through the glass the wall behind it was perfectly clear. The problem is the decoration stained, worst of all larger rocks (not large but well above pebel size). It's ironic you should mention chernobyl. The gravel i use is black and when i put some of the larger rocks back in, they literally glowed. Some of the decorations got pained as well, which combined with the rocks gave the cheesy neuclear movie look. The carbon fixed the water didn't fix the decor unfourtunetly.

Well I'll certainly do that from now on
